My research focuses on adolescents from marginalized groups (e.g., youth of color) who often need to navigate the challenges of racism and discrimination. A core question my work seeks to answer is how to alleviate the negative impacts of discrimination and promote the development of these adolescents by leveraging protective factors at socio-cultural, bio-behavioral, and cognitive levels. One of my current projects investigates how multiple forms of discrimination (based on one's race/ethnicity, immigration status, sexual orientation, weight) may contribute to adolescent substance use, and how these effects may be alleviated by neighborhood environment and everyday sleep, using national data from the on-going Adolescent Brain Cognitive Development (ABCD) Study. Another project examines how adolescents' daily experiences related to race/ethnicity interact with their sleep and cognitive functioning to influence everyday psychological and academic outcomes.
